OPA-based policy engine for AI agents blocking injection and tool abuse.
Catches when authorized agents are being manipulated, not just blocking unauthorized access.
Execution firewall for AI agents before prompt injection causes real damage.
IFC + capabilities block prompt injection at execution sinks, not input filters—40yr research applied.
Streaming guardrail catches semantic PII that regex misses — based on real LangChain issues.
Deterministic prompt linter flags injection, exfiltration, obfuscation before LLM runs—treats prompts as executable code.
